We started running amt tests in the netdev CI, and it looks like it hangs - or at least it doesn't produce any output for long enough for the test runner to think it hung. While looking at the logs, however, I see: [ 3.361660] smcrouted[294]: segfault at 7fff480c95f3 ip 00000000004034e4 sp 00007fff480b9410 error 6 in smcrouted[402000+a000] likely on CPU 3 (core 3, socket 0) [ 3.361812] Code: 74 24 38 89 ef e8 4c 33 00 00 44 0f b7 f8 66 39 84 24 e2 01 00 00 75 09 45 85 ed 0f 85 ed 01 00 00 48 8b 44 24 38 0f b6 40 33 <42> 88 84 3c e4 01 00 00 48 8b 3b 48 8d 54 24 38 48 8d 74 24 50 e8 https://netdev-3.bots.linux.dev/vmksft-net/results/577882/4-amt-sh/ So I think the cause may be a bug in smcroute. We use smcroute build from latest git # cd smcroute/ # git log -1 --oneline cd25930 .github: use same CFLAGS for both configure runs # smcroute -v SMCRoute v2.5.6 Could you check if you can repro this crash?
